Hp manifolds

Hi-po's in an early A with a 451/B. Cant claim they will fit a taller 440 but you can see where the steering is. I took a slight angle cut off these, but am wondering if the studs will not 'fit' on a different style with the large through hole for the exhaust bolt? Forget power steering in this app.
